Talk:Using RXTX

From Rxtx

error with finding files

Hi,

I followed the linux installation of the rxtx libraries, and placed the librxtxSerial.so and the RXTXcomm.jar in the right directories.

I have set the CLASSPATH, the JAVA_HOME and the LD_LIBRARY_PATH directories ok.

but when I run the following application, I seem to not find the right library. is there any reason for this?

thanks, John
